Windows XP with port 445 open allows remote attackers to cause a denial of service (CPU consumption) via a flood of TCP SYN packets containing possibly malformed data.


The SYN cache (syncache) and SYN cookie (syncoo

cache | SYN |

The SYN cache (syncache) and SYN cookie (syncookie) mechanism in FreeBSD 4.5 and earlier allows remote attackers to cause a denial of service (crash) (1) via a SYN packet that is accepted using syncookies that causes a null pointer to be referenced for the socket's TCP options, or (2) by killing and restarting a process that listens on the same socket, which does not properly clear the old inpcb pointer on restart.

MailServer | attackers | service | denial | allows | remote | Kerio | cause |

Kerio MailServer 5.0 allows remote attackers to cause a denial of service (hang) via SYN packets to the supported network services.


Microsoft Windows 2000 allows remote attackers

Microsoft | Windows |

Microsoft Windows 2000 allows remote attackers to cause a denial of service (memory consumption) by sending a flood of empty TCP/IP packets with the ACK and FIN bits set to the NetBIOS port (TCP/139), as demonstrated by stream3.

Surfboard | Motorola |

Motorola Surfboard 4200 cable modem allows remote attackers to cause a denial of service (crash) by performing a SYN scan using a tool such as nmap.


Kerio Personal Firewall (KPF) 2.1.4 and earlier

Firewall | Personal | Kerio |

Kerio Personal Firewall (KPF) 2.1.4 and earlier allows remote attackers to cause a denial of service (hang and CPU consumption) via a SYN packet flood.

simulated | addresses | attackers | identify | packets | replies | allows | remote | Honeyd | before | being | flags | which | SYN | TCP | set | RST |

Honeyd before 0.8 replies to TCP packets with the SYN and RST flags set, which allows remote attackers to identify IP addresses that are being simulated by Honeyd.


The firewall in Astaro Security Linux before 4.

Security | firewall | before | Astaro | Linux |

The firewall in Astaro Security Linux before 4.024 sends responses to SYN-FIN packets, which makes it easier for remote attackers to obtain information about the system and construct specialized attacks.
